MP-7 MEDIUM

Pectin is an important cell wall component of higher plants that helps in cementing plant cells together. Most pectin-degrading organisms are associated with raw agricultural products and with soil. These organisms are known as pectinolytic organisms since they possess pectin lyase that degrades pectin. Detection of pectinolytic activity of an organism is carried out either by observing depression in the gel around the colony where the substrate has been degraded or by flooding the plate with a precipitant solution. MP-7 Medium is used for detecting pectinolytic organisms especially those producing pectate lyase. MP-7 medium is recommended by APHA for detecting pectinolytic organisms.

for cultivation of pectinolytic microorganisms especially those producing pectate lyase
